Description Of Tests

The QUICK TEST diagnostic procedure is a functional test of the EEC-IV system. It consists of 4 basic test steps. These basic steps must be carefully followed in sequence, otherwise misdiagnosis, or replacement of non-faulty components may result.

PREPARATION and EQUIPMENT HOOK-UP .
KEY ON/ENGINE OFF (KOEO) SELF-TEST .
KEY ON ENGINE RUNNING (KOER) SELF-TEST .
CONTINUOUS MONITOR SELF-TEST (WIGGLE TEST) .

After all tests, servicing, or repairs have been completed, repeat QUICK TEST to ensure all EEC-IV systems work properly.

The KOEO and KOER SELF-TESTS are intended to detect faults present at the time of testing, not intermittent faults. Intermittent faults are detected by CONTINUOUS SELF-TEST and stored in the ECA memory.

NOTE: Correct test results for system are dependent on the correct operation of several related non-EEC components and systems. All non-EEC problems should be corrected before attempting to diagnose the EEC system.
